Recovery of gifts

Hi, I am from India and my friend has filed a false case on me saying that I promised him of marriage and he gave me money and gifts and now because I am not marrying him he want to recover the money and gifts back but that is not true. I trusted him and he did use to Tranfer money to my account and my family account and take cash from us because he said he need cash and we trusted him because he was my friend and during this time we invested in a Bussiness togather and I have a Bussiness partner ship deed from him and a cheque signed from him as a security to the money he is taking from me as a investment and the money he took from me as cash and I have also loaned him 5.5 lac and I Tranfered this to his account now this happened in year 2016,17,18 and since 3 years he is always saying that he will pay me back but he did not so we had a fight and now he filed a cheating case on me and trying to sue me and denying of taking cash from me he said he Tranfered amount into my account and lied about taking cash from me and my family. And he also said that he gifted me gold which is only little item on my birthday and I also gifted him a gold chain on his birthday in return. But now because of lack of proof from my side has blackmailed me and asked money he said he would file a case if I don’t give him money but I denied so he filed a case now and I am so worries and shocked that my friend whom I trust so much has done this. Because I am a girl and he know how society treats a girl when such type of allegations are made on girl. I want to know if he really can sue me legally for money he voluntarily Tranfered and I have never asked for a loan from him and he took cash from me for those those Tranfers. Please advice.
